Great Dark Spot

Beyond the ansa of Saturn's rings, a crescent Rhea completes this ring-and-moon composition. Rhea (1,528 kilometers, or 949 miles across) is near the middle of the bottom of the image. This view l...

The tip of the shadow of the moon Tethys is cut off where it crosses Saturn's B ring, demonstrating the variations in density across the planet's rings. Most of Tethys' shadow is seen lying across...

Cassini looks toward northern latitudes on Saturn and out across the ringplane. This infrared view probes clouds beneath the hazes that obscure the planet's depths in natural color views. This ima...

Tethys passes silently between Saturn and Cassini as a train of storms rumbles through the planet's southern hemisphere. The rings' shadows darken the planet at top. Tethys is 1,062 kilometers (6...

Artist's concept of the Dawn spacecraft gathering spectral data from Vesta.

This image shows that NASA's Dawn mission detected abundances of hydrogen in a wide swath around the equator of the giant asteroid Vesta. The hydrogen probably exists in the form of hydroxyl or wat...

Atmospheric Detail in Infrared July 13, 2004 Full-Res: PIA05415 Cassini captured intriguing cloud structures on Saturn as it near...

Titan and Saturn have few things in common, but a hazy, clouded appearance is one feature they share.

This image of a large block along the ridge of Urvara Crater was obtained by NASAs Dawn spacecraft on July 24, 2018 from an altitude of about 36 miles (58 kilometers).

From the Dark Side December 10, 2004 Full-Res: PIA06529 As Cassini swung around to the dark side of the planet during its first close ...

Possible variations in chemical composition from one part of Saturn's ring system to another are visible in this Voyager 2 image as color variations that can be enhanced with special computer-proce...

Intriguing Enceladus November 29, 2004 Full-Res: PIA06531 This Cassini view of Enceladus hints at the curvilinear, groove-like fea...

This detailed look at Saturn's A ring captures Daphnis in the narrow Keeler Gap. The small moon creates complex wave patterns in the gap edges that Cassini scientists are working to understand. To...

As it swooped past the south pole of Saturn's moon Enceladus on July 14, 2005, Cassini acquired high resolution views of this puzzling ice world.

This image of Urvara Crater's ridge on Ceres was obtained by NASA's Dawn spacecraft on July 5, 2018 from an altitude of about 75 miles (121 kilometers).

These two side-by-side images compare a "twisted" sea-floor spreading feature on Earth, known as an Offset Spreading Center (OSC), to a very similar looking twisted break, or axial discontinuity, i...

A pair of Saturn's small moons, Janus and Pandora, accompany the planet's rings in this Cassini spacecraft image presenting the view in dramatic diagonal fashion. The rings are between the two moo...

This trio of Junocam views of Earth was taken during Juno's close flyby on October 9, 2013.

Of all the planets NASA has explored, none have matched the dynamic complexity of our own.

Ithaca Chasma rips across Tethys from north to south near the center of this view. The moon's western limb is flattened, indicating the rim of the giant impact basin Odysseus. The dark, east-west ...

Huygens probe jettison, another view April 20, 2004 Highest Resolution Available This artist's rendition shows the Huygens probe a...

The Cassini spacecraft looks toward high northern latitudes on Saturn and the wild cloud forms that swirl there. The view was taken from about 23 degrees above the ringplane and looks toward the u...

Hovering Mimas September 16, 2004 Full-Res: PIA06478 Saturn's moon Mimas hangs in the sky above Saturn's rings in this Cassini spa...

This image from NASA's Dawn spacecraft shows undulating terrain, located only in asteroid Vesta's southern hemisphere, in and around the Rheasilvia impact basin.

This view of the volcanic plains of Neptune's moon Triton was produced using topographic maps derived from images acquired by NASA's Voyager spacecraft during its August 1989 flyby, 20 years ago th...
